You will get a Full Stack solution (any size - both frontend and backend
Project details
I have been doing server/client, cloud, and internet full stack services since long before it was termed full stack - In fact I started this before the internet became commonplace - yes there were networks and servers and client using what became known as stacks before the term. :) I have many years of experience with a number of popular stack solutions - see portfolios. Been a successful freelancer my full career of 35+ years. First time hired as a freelancer was when I was 14 years old to rewrite the telecommunications software for my school board. Been working on these things ever since then.
